An antenna arrangement for a GPS signal processing device having a circuit board is disclosed. For this purpose, the present invention decodes a transport stream packet and reads additional information with respect to a user desired audiovideo packet from program specific information, and inserts and stores the read result in a particular region of the audiovideo packet and parses the additional information to perform a searching. A knee point voltage may be applied to the photodiode and resets a voltage on the photodiode to the knee point voltage when the voltage on the photodiode falls below the knee point voltage. The data generator for generating SONETSDH type data frames.
